A method comprises continuously supplying an alcohol to a pressurized reaction system, pressurizing carbon monoxide with a compressorattached to a first feed line, for continuously supplying carbon monoxide to the reaction system via a second feed linewith a reference flow rate F, and converging excess carbon monoxide in the reaction system in the first feed line via a branched circulation linefor allowing to react alcohol with carbon monoxide. The reference flow rate F in the second feed lineis a total rate of a reference consumption flow rate Fcs in the reaction and a flow rate Fin excess rate over a fluctuation consumption flow rate &#x394;Fcv in the reaction system (F=Fcs+F, F&#x3e;&#x394;Fcv). According to the pressure fluctuation of the gaseous phase in the reaction system, the flow rate in the circulation lineis controlled to a flow rate Fr=F&#x2212;&#x394;Fcv and the feed flow rate in the first feed lineis controlled to a flow rate Fsu=Fcs+&#x394;Fcv, for compensating a consumption rate variation in the reaction system with the feed flow rate of carbon monoxide. This ensures discharge inhibition of the gaseous reactant in a liquid phase pressurized reaction system (such as carbonylation reaction system) and effective utilization of the reactant for the reaction.

The invention provides a circulating type bank note depositing and dispensing machine with which the progress of depositing and dispensing is made visible from a customer side, speeding up the temporary storage of deposited bank notes and facilitating the return of the temporarily stored bank notes if the deposit is not approved. The bank note depositing and dispensing ports are disposed on the upper side of the machine body, making it possible for a customer to observe or check the progress of a deposit or dispensing. Temporarily stored deposited bank notes are disposed in the front side area of the machine body, and if the deposit is not approved, the front side door of the temporary storage portion opens to allow the temporarily stored bank notes to be taken out from the front side of the machine body, facilitating the quick return of the temporarily stored bank notes.
